Make the chipotle sauce: In a small bowl, combine ¼ cup mayonnaise, ¼ cup sour cream, 2 tablespoons minced cilantro, 2 teaspoons garlic powder, and 1 tablespoon lime juice. Add 3 chipotle peppers in adobo sauce, chopped, plus 2 tablespoons adobo sauce** and ½ teaspoon ground cumin (if using). Season to taste with salt and pepper. If desired, add more chipotle pepper for a spicier sauce. Serve and enjoy!Note: The sauce should taste creamy, tangy, well-salted, with a bit of heat. I typically add 4 chopped peppers for moderate heat, but you can add as much or as little as you like!
Notes
** Chipotle peppers often have a lot of seeds in them, so I do try to remove most of the seeds before adding them to the sauce.Leftover sauce can be stored in the fridge in an airtight container for 5 - 7 days.
